The 4132A016 (also catalogued as ULPK0040 bare pump) is a mechanical diaphragm fuel lift pump designed for Perkins 1004-4 and 1004-4T naturally aspirated and turbocharged engines. These 4.0L, 4-cylinder engines are fitted to:

• Massey Ferguson 6400- and 7400-series tractors
• Landini Legend 105/115 row-crop machines
• JCB 4CX backhoe loaders and 530-70 Loadall telehandlers
• FG Wilson P22-6 and Pramac GSW85P skid-mounted generator sets

The pump mounts on the left-hand timing-gear cover and feeds the high-pressure injection pump across engine speeds from 800 r/min idle to rated 2,200 r/min.

• Nominal delivery: 110 L/h at 350 kPa and 2,000 r/min
• Inlet/outlet ports: 8 mm hose-barb fittings
• SAE J744 size 1 flange with two M8 threaded holes on 60 mm centers
• Driven directly by camshaft eccentric
• Diaphragm diameter: 76 mm
• Stroke: 5 mm
• Internal bypass valve limits pressure to 400 kPa
• All sealing gaskets are FKM (Viton) for biodiesel compatibility up to B20
• Arctic-grade diesel compatibility down to -40°C

• Powder-coated aluminium housing resists salt spray and stone chips
• Multi-layer fabric-reinforced nitrile diaphragm faced with PTFE for low swell and extended flex life
• Actuating lever and push-rod: induction-hardened medium-carbon steel
• Internal return spring: stainless steel to prevent sag in high-humidity environments
• Transparent sediment bowl with 80 µm replaceable paper element
• Spring-loaded priming lever for easy manual bleeding after filter changes
• Lightweight, maintenance-free sealed bearings
• Low noise signature ideal for continuous-duty applications
